Technical field
The utility model relates to a kind of thermopair, more particularly, relates to a kind of anticorrosion armoured thermocouple.
Background technology
Thermopair is as a kind of temperature test instrument, need often to touch corrosive gas, corrosive liquids etc. in test process, but existing thermopair is when Long contact time is to corrosive gas or liquid, can not thermocouple wire be prevented preferably to be corroded, thermocouple wire is shortened serviceable life.
Utility model content
The technical problems to be solved in the utility model is, for the above-mentioned defect of prior art, provides a kind of anticorrosion armoured thermocouple.
The utility model solves the technical scheme that its technical matters adopts: construct a kind of anticorrosion armoured thermocouple, this thermopair comprises protection jacket layer, anticorrosion jacket layer and is positioned at the thermocouple wire of this anticorrosion jacket layer, this protection jacket layer and this anticorrosion jacket layer are hollow columnar structures, this protection jacket layer end is provided with opening, this anticorrosion jacket layer is inserted in this protection jacket layer from this opening part, and this anticorrosion jacket layer end is provided with the sealing-plug snapping in this opening part.
In anticorrosion armoured thermocouple described in the utility model, sealing plug and this anticorrosion jacket layer are anti-corrosion material and make.
In anticorrosion armoured thermocouple described in the utility model, sealing plug is threaded with this protection jacket layer distal opening.
In anticorrosion armoured thermocouple described in the utility model, this protection jacket layer inner wall at end is provided with the stop section to stopping sealing plug.
In anticorrosion armoured thermocouple described in the utility model, this protection jacket layer is the protection jacket layer that ceramic corundum or carbofrax material are made.
In anticorrosion armoured thermocouple described in the utility model, this protection jacket layer sidewall is provided with the bleeder vent running through this protection jacket layer.
Implement anticorrosion armoured thermocouple of the present utility model; there is following beneficial effect: when using anticorrosion armoured thermocouple of the present utility model; anticorrosion jacket layer is inserted in protection jacket layer; then sealing-plug is snapped in in protection jacket layer distal opening; be fixedly connected with anticorrosion jacket layer in protection jacket layer; in use; when thermopair touches corrosive gas or liquid; anticorrosion jacket layer can be positioned at the thermocouple wire protecting jacket layer by available protecting; prevent thermocouple wire to be corroded, increase the serviceable life of thermopair.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described in further detail, in accompanying drawing:
Fig. 1 is the structural representation of the anticorrosion armoured thermocouple of the utility model.
Embodiment
For making the purpose of this utility model, technical scheme and advantage clearly, below in conjunction with accompanying drawing, the utility model embodiment is described in further detail.
As shown in Figure 1, in anticorrosion armoured thermocouple first embodiment of the present utility model, this thermopair 1 comprises protection jacket layer 2, anticorrosion jacket layer 3 and is positioned at the thermocouple wire 4 of this anticorrosion jacket layer 3, this protection jacket layer 2 and this anticorrosion jacket layer 3 are hollow columnar structures, this protection jacket layer 2 end is provided with opening 5, this anticorrosion jacket layer 3 is inserted in this protection jacket layer 2 from this opening 5, and this anticorrosion jacket layer 3 end is provided with the sealing-plug 6 snapping in this opening 5 place.
When using anticorrosion armoured thermocouple 1 of the present utility model; anticorrosion jacket layer 3 is inserted in protection jacket layer 2; then sealing-plug 6 is snapped in in protection jacket layer 2 distal opening 5; be fixedly connected with anticorrosion jacket layer 3 in protection jacket layer 2; in use, when thermopair 1 touches corrosive gas or liquid, anticorrosion jacket layer 3 can be positioned at the thermocouple wire 4 protecting jacket layer 2 by available protecting; prevent thermocouple wire 4 to be corroded, increase the serviceable life of thermopair 1.
Further, sealing plug 6 and this anticorrosion jacket layer 3 are anti-corrosion material and make.In use, can need according to difference the anticorrosion jacket layer 3 of selecting different anti-corrosion material to make, such as, in the coking furnace adopting combustion of natural gas heating, adopt the anticorrosion jacket layer 3 that silicon dioxide is made.
Further, sealing plug 6 is threaded with this protection jacket layer 2 distal opening 5.In other embodiments, also can adopt interference fit at that time, sealing-plug 6 was snapped in in opening 5.
Further, this protection jacket layer 2 inner wall at end is provided with the stop section 7 to stopping sealing plug 6.
Further, this protection jacket layer 2 is the protection jacket layer 2 that ceramic corundum or carbofrax material are made.
Further, for making thermopair 1 thermometric more rapid, this protection jacket layer 2 sidewall is provided with the bleeder vent 8 running through this protection jacket layer 2.During use, high-temperature gas enters in thermopair 1 by bleeder vent 8, and thermocouple wire 4 contacts with high-temperature gas fast, accelerates the intensification of thermocouple wire 4.
The foregoing is only embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every utilize the utility model instructions and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
